Description

Technical Field

[0001] This utility model relates to the field of mixing equipment, specifically a mixing equipment for an automatic pelletizing production line. Background Technology

[0002] In the automated pelletizing process, it is usually necessary to use a mixing device to thoroughly mix the powder with the corresponding liquid. However, the existing automated pelletizing production line mixing equipment takes a long time to fully wet the powder, and there is a blind zone at the discharge valve at the conical bottom of the mixing tank, resulting in sedimentation and non-dispersion, which affects subsequent material discharge. Utility Model Content

[0003] The purpose of this invention is to provide an automatic pelletizing production line mixing device to solve the above-mentioned problems.

[0004] This utility model achieves the above-mentioned objectives through the following technical solution: an automatic pelletizing production line mixing equipment includes a mixing tank, a reducer for driving the mixing structure, a feeding hopper, and a liquid injection pipe. A fixed cover plate is fixedly installed at the opening of the mixing tank, and the feeding hopper is connected to the fixed cover plate. The middle part of the fixed cover plate is fixedly connected to the reducer. A wet material spray pipe connected to the liquid injection pipe is located directly below the port of the feeding hopper. A transmission screw is installed at the output end of the reducer, and an internally threaded short pipe is threadedly connected to the transmission screw. Stop nuts are provided at both sides of the holes on the internally threaded short pipe. The bottom end of the convex structure on the surface of the internally threaded short pipe is located near the middle of the bottom of the mixing tank. Spray heads are inclined downwardly distributed on the wet material spray pipe.

[0005] Preferably, the injection pipe is connected to a wet material spray pipe and a cleaning spray pipe respectively through the same three-way valve, and the cleaning spray pipe is installed in a ring shape on the ring wall inside the mixing tank.

[0006] Preferably, a pneumatic quick-install ball valve and a pneumatic slide gate valve are respectively installed on one side of the conical surface and the bottom of the mixing tank.

[0007] Preferably, one side of the fixed cover plate is movably connected to one side of the folding cover plate via a hinge, and the folding cover plate is connected to another part of the opening of the mixing tank via a locking fastener.

[0008] Preferably, the stop nut is threadedly connected to the transmission screw portion located in the side hole.

[0009] Compared with the prior art, the advantages of this utility model are:

[0010] The liquid is sprayed downwards at an angle through the irregularly shaped wet material spray pipe connected to the spray head. The irregularly shaped wet material spray pipe is located directly below the feed hopper connection port, which can quickly humidify the material entering the mixing tank, effectively shorten the time required for subsequent material mixing and full humidification, and at the same time reduce powder flying.

[0011] The stirring rod position can be adjusted by connecting the internally threaded short tube to the drive screw and by using adjustable stop nuts distributed on the top and bottom. This is suitable for stirring tanks of different depths. At the same time, the bottom of the convex structure on both sides of the internally threaded short tube is close to the bottom of the stirring tank, which solves the problem of sedimentation blind spots at the bottom of the conical tank and prevents lumps from forming and clogging the valve port.

[0018] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] Please see Figure 1-4 As shown, an automatic pelletizing production line mixing device includes a mixing tank 1, a reducer 2 for driving the mixing structure, a feed hopper 5, and a liquid injection pipe 6. A fixed cover plate 7 is fixedly installed at the opening of the mixing tank 1. The feed hopper 5 is connected to the fixed cover plate 7. The middle part of the fixed cover plate 7 is fixedly connected to the reducer 2. A wet material spray pipe 620 connected to the liquid injection pipe 6 is located directly below the port of the feed hopper 5. A transmission screw 210 is installed at the output end of the reducer 2, and an internally threaded short pipe 220 is threaded onto the transmission screw 210. Stop nuts 222 are provided at the two side holes 221 on the internally threaded short pipe 220. The bottom end of the convex structure on the surface of the internally threaded short pipe 220 is close to the middle position of the bottom of the mixing tank 1. Spray heads 621 are inclined downwardly distributed on the wet material spray pipe 620.

[0022] The injection pipe 6 is connected to the wet material spray pipe 620 and the cleaning spray pipe 610 respectively through the same three-way valve. The cleaning spray pipe 610 is installed in a ring shape on the ring wall inside the mixing tank 1. The three-way valve switches between opening and closing so that different liquids can enter the wet material spray pipe 620 and the cleaning spray pipe 610 respectively.

[0023] A pneumatic quick-install ball valve 3 and a pneumatic slide gate valve 4 are respectively installed on one side of the conical surface and the bottom of the mixing tank 1. The pneumatic quick-install ball valve 3 and the pneumatic slide gate valve 4 facilitate the discharge of materials.

[0024] Furthermore, one side of the fixed cover plate 7 is movably connected to one side of the folding cover plate 8 via a hinge, and the folding cover plate 8 is connected to the other part of the opening of the mixing tank 1 via a locking fastener 9.

[0025] Furthermore, the stop nut 222 is partially threaded to the transmission screw 210 located in the side hole 221.

[0026] The difference between this utility model and the existing technology lies in: combining Figure 2 As shown, liquid is sprayed downwards at an angle through the spray head 621 connected to the irregularly shaped wet material spray pipe 620. Combined with the fact that the irregularly shaped wet material spray pipe 620 is located directly below the connecting port of the feed hopper 5, the material entering the mixing tank 1 can be quickly humidified, effectively shortening the time required for subsequent material mixing and full humidification, while reducing powder flying.

[0027] Combination Figure 3 and Figure 4 As shown, the internally threaded short pipe 220 is threadedly connected to the transmission screw 210, and combined with the adjustable stop nuts 222 distributed vertically, the position of the stirring rod 230 can be adjusted, which can meet the needs of stirring tanks 1 of different depths. At the same time, the bottom ends of the convex structures on both sides of the internally threaded short pipe 220 are close to the bottom of the stirring tank 1, which solves the problem of sedimentation blind zone at the bottom of the conical tank and avoids blockage of the valve port by lumps.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
